What I personally do is bind transformation to numpad4 and use xpadder, toggle the turbo option on the button used to simulate numpad4 so it does turbo by itself with no need to interfere with battle to press the simulated numpad4 button. Don't even need to press it again when I go to the next dungeon. I just gotta remember to turn toggle off before I get in town or risk flying in midair with flashy lights around me. :3c
